Researchers evaluating severe malaria in pediatric patients have found that mean left ventricular mass does not differ significantly between infected children and healthy controls, according to a cross-sectional analytical study.
Evaluating Left Ventricular Mass and Cardiac Indices in Paediatric Malaria
The study evaluated 100 children with severe malaria alongside 100 apparently healthy controls ranging in age from 6 months to 6 years. Participants were recruited from two tertiary hospitals to assess left ventricular mass (LVM), left ventricular mass index (LVMI), and related structural and functional indices using echocardiography. Data analysis utilized IBM SPSS version 25, which included exploratory regression analyses.
Results showed that mean LVM did not differ significantly between the severe malaria group and the control group, recording 38.38 ± 17.93 grams versus 40.28 ± 18.58 grams with a p-value of 0.466. While the manuscript noted left ventricular hypertrophy frequencies of 10% in children with severe malaria compared to 4% in controls, the direct LVH classification variable was absent from the supplied analytic CSV, preventing independent verification of the original significance statistic.
Severe Malaria Patients Show Lower Ejection Fraction and Elevated Pulmonary Pressure
Secondary cardiac indices revealed distinct differences between the two cohorts. The mean left ventricular ejection fraction (LVEF) was lower in children with severe malaria at 65.58 ± 13.17% compared to 69.00 ± 9.85% in healthy controls, yielding a p-value of 0.039.
Conversely, mitral annular plane systolic excursion (MAPSE) registered higher in the severe malaria group at 14.38 ± 4.10 mm versus 13.31 ± 2.28 mm in controls, with a p-value of 0.024. Estimated pulmonary pressure was also elevated among the severe malaria patients, measuring 17.03 ± 5.86 mmHg compared to 14.47 ± 3.89 mmHg in the control group.
Assessing Malarial Anaemia and Body Growth Impact on Heart Structure
The available data do not support severe malarial anaemia as an independent driver of increased left ventricular mass. Exploratory adjustment for age and sex demonstrated that age remained strongly associated with LVM.
Researchers noted that this statistical relationship highlights the necessity of accounting for growth and body size during pediatric cardiac assessments.
